the number of protons and electrons are the same. on the Periodic Table of Elements you will see your element that you are looking for, then you will see there is a number under it. )ex. 9=flourine) that number is the number of protons. then, usually the number of protons, electrons, and neutrons are the same.

∙ 12y agoThe atomic number of an atom refers to the proton number, which is the number of protons the atom has in the nucleus.
One must take note that an atom is always electrically neutral. As such, an atom will always have the same number of protons and electrons.
Judging by that, the atom of the element which has 17 electrons has 17 protons too. The element you are referring to is chlorine (Cl).

∙ 11y agoThe number of protons and electrons is equal to the atomic number. So if the atomic number is 17 then there are 17 protons and 17 electrons. The element is chlorine.

∙ 11y agoThe atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.

Chlorine has atomic number 17 and mass number 35?
The atomic number tells you that chlorine atoms have 17 protons. If you know the mass number and atomic number, you can use subtraction to determine the number of neutrons like this: mass number - atomic number = 35 - 17 = 18. A neutral atom has equal numbers of protons and electrons. I'm guessing this is a neutral chlorine-17 atom, so it also has 17 electrons. So, and atom of chlorine-17 has 17 protons, 17 electrons, and 18 neutrons.
What is the atomic number of Cl2?
There is no number for Cl2.Element Cl has 17 atomic number.
How many protons neutrons and electrons are in chlorine 39?
The number of protons and electrons is always the same as the atomic number, which for chlorine is 17. The number of neutrons is always the mass number minus the atomic number, which for this isotope is also 17.
What element has atomic number 16 and has 18 electrons?
SULFUR has 16 protons.But no neutral atom of an element can have MORE Electrons than Protons. This means that NO element can have 16 Protons and 18 Electrons.
What are the atomic number and mass number if the number of electron in an element oxygen is 8 and the number of neutrons is 9?
The atomic number is 8 (the number of protons, which for oxygen is equal to the number of electrons) and the mass number is 17 (the combined number of protons and neutrons).
